In the study, researchers looked at ways to save water while growing orange trees in Mediterranean regions where water is limited. They tried different irrigation methods on orange trees in Spain for nine months. They found that a method called controlled deficit irrigation reduced water use by 5% compared to normal irrigation, while boosting production by 4%. By using this method, they were able to determine that between 700 and 800 mm of water is best for the trees. This means that controlled deficit irrigation can help save water without hurting the amount or quality of the fruits grown. Overall, this strategy can be a good way to manage crops and support sustainability.
